FIELD: method and device for quasicontinuous determination of coefficient of saturation of hot solutions with sylvite. SUBSTANCE: coefficient of saturation with sylvite of hot solution produced during separation by dissolving of potassium raw salt is determined with the help of transducers using transverse piezoelectric effect or sound velocity transducer. The process of separation and crystallization is controlled automatically. EFFECT: higher efficiency. 4 cl, 4 dwg
